+`grpc_recovery` are intereceptors that recover from gRPC handler panics.

+Server Side Recovery Middleware
+
+By default a panic will be converted into a gRPC error with `code.Internal`.
+
+Handling can be customised by providing an alternate recovery function.
+
+Please see examples for simple examples of use.
